2 Claims. (01. 296-445) My invention relates to a guideway or channelstructure for the edges of a glass pane and is particularly adapted foruse in the door or window frames of vehicles, although it is not limitedthereto. More particularly, my invention relates to the combination of achannel member of the above type and a sheath structure for such member.

One object of my invention is to .provide a guideway or channel for theopposing side edges of a vertically movable pane of glass which provides a means for gripping the side surfaces of the glass to preventlateral movement thereof under normal conditions, but will, permit ready0 vertical movement of the pane of glass, together with a sheathstructure adapted to cover and protect the entire outer surface of thechannel or guideway, the sheath structure being also adapted to concealthe free edges of the channel.

Another object of my invention is to provide a sheath structure forcovering a channel of the above type which serves not only as aprotecting means for the outer surface of the channel but, at the sametime, serves as a means for locking the channel member in the groove inwhich it is disposed when in operative position.

Still another object of my invention is ,to provide a sheath structurethat not only serves as a protecting means for the channel member and asa means for concealing the free edges of the channel member, but alsoserves as a means for strengthening the member.

Various other objects of my invention will appear in the followingdetailed description and one embodiment thereof may be seen in theaccompanying drawing wherein similar characters of reference designatecorresponding parts, and wherein;

Fig. l is a perspective view showing a guideway or channel member and asheath constructed in accordance with my invention, the combinationbeing disposed within a groove that forms a part of a door or windowframe and containing a pane of glass.

Fig. 2 is a perspective view of the sheath structure shown in Fig. 1.

Fig. 3 is a view similar to Fig. 1, but showing a modified form ofsheath structure.

Fig. 4 is a perspective view of the sheath structure shown in Fig. 3.

In the drawing, I have shown a section 1 of a door or window frameprovided with spaced members or rabbets 2 that, together with the frame1, form the usual groove 3 for the reception of a frame surrounding apane of glass or for the reception of guideways or channel members forsuch glass. As shown in Figs.

1 and 3, a guideway or channel member conmaterial collects dust and dirtand becomes more or less permanently dingy and dirty in appearance. Thisis particularly true of the free ends of the channel member that arevisible to an ordinary observer. Therefore, in accordance with myinvention, to protect the fabric on the free ends of the channel memberside walls as 'well as to protect the fabric over the entire outersurface of the channel member to provide means for locking the channelmember in the groove 3 and to give the channel member additionalstrength, I provide a suitable sheath 9 adapted to surround the channelmember and protect the same without interfering with the usual operationof the channel member as a guideway for the glass pane 8.

As shown in Fig. 2, the sheath member 9 preferably consists of a flatsheet of relatively thin and resilient metallic material having itsopposing ends or edges bent as at 10. In the use of this sheathstructure, the sheath 9 is placed over the groove 3 and the channelmember or guideway is placed on the fiat portion thereof intermediatethe bent end portions 10. Then the edge of a pane of glass 8 is placedthereupon and the sheath structure 9 and the channel member or guidewayare forced downwardly into the groove 3 whereby the sheath structure isbent to surround the channel member with the bent end portions 10engaging the free ends of the channel member and forming beads asshownin Figs. 1 and 3, and the free ends of the channel member resilientlyengaging opposite sides of the pane.

As hereinbefore stated, the metallic core 4 consists of a length ofmetallic strip bent until it is substantially C-shaped in cross sectionwith its free edges adjacent each other. With this construction, theguideway or channel member and the sheath structure 9 being resilient,upon being inserted into the groove 3 as hereinbefore described, willmaintain themselves within the groove without additional fasteningmeans.

' Further, a pane of glass having-itsone sideredge inserted into theguideway or channel member.

shown in Figs. 1 and 3 will be gripped in the free edges of the channelmember and maintained in position in such manner as to prevent lateralmovement of the pane but to permit read vertical movement thereof.

Referring to Figs. 3 and 4 of the drawing, I have shown a modified formof sheath structure wherein the body portion of the sheath itself is ofan angular form with a flat portion 11 adapted to rest on the surface ofthe frame 1, fiat portions 12 adapted to bear against the side surfacesof the channel member or guideway along a portion of the length of suchsurface, flat portions 13 also adapted to bear against the side surfacesI have provided a sheath structure embodying For instance,

numerous advantageous features. I have provided a sheath structureinwhich the channel member or guideway, fits and which is adapted, tocover and protectflthe entire outer surface of the channel member or'guidewayg I have also provided a sheath structure of such' nature thatthe opposing free ends of the 'chan nel or guideway which are adapted togrip the opposing side edges of the pane of glass Bjwheri a channelmember and pane are inserted in the groove 3 of such nature that theopposing free ends of the channel member will be concealed from the viewof an ordinary observer, the beads orbent portions of the sheathstructures serving this purpose.

In addition to the advantageous features hereinbefore mentioned, I haveprovided a sheath structure which inherently increases the strength ofthe channel member or guideway the channel member firmly within thegroove 3.

advantageous features will "be" readily Y v apparent. r What I claim is:3 y i 1. In combination with *ajwindow frame ,having a generallychanneleshaped groove, of a window-receiving channel structure, adaptedto be arranged in said groove and having a base and a pair-of yieldingside walls, the free outer end portions of said side walls being turnedlaterally toward each other for yieldingly receiving a window panetherebetween, and a separate, resilient sheet metal sheath for saidchannel structure, said sheath having a base and a pair of side wallsthe base of said sheath being adapted to be interposed between thebottom of said groove, and the base of said channel structure and theside walls of'said sheath being adapted to be interposed between thesides of said groove and the side walls of said channel structure, the

free outer end portions of said sheath side walls projecting outwardlybeyond the side walls of,

said groove and the side walls of said channel structure andterminatingin inwardly converging flanges whichyieldingly engage thelat'erallyturned free outer end portions of said channel structure side walls inspaced relation to the glass-receiving ends thereof.

2. In combination with a windowifrarnei having a generallychannel-shaped-groove, of a window-receiving channel structureaadaptedfto be;

arranged in said groove and having a baseand a pair of yielding sidewalls, the free-outer end portions of said sidewalls being turnedlater-v ally toward each otherfor'yieldingly receiving aflwindow panetherebetween, and aseparate, resilient sheet metal sheath for' saidchannel structure, said sheath having a base and a pair of sidewalls,the base of said sheath being adapted to be interposed 'between thebottom of said groove and the base of said channel structure and theside walls of said sheath being adapted to'be interposed between thesides of said groove and the side walls of said channel structure, thefree outer endiportions of said sheath side walls projecting outwardlybeyond the side walls of said groove (and the side walls of said channelstructur'ejand terminating in inwardly converging flanges whichyieldingly engage the laterally turne free outer end portions of saidchannelstruct sidewalls in spaced relation to thejgla'ssfr v ng endsthereof, said sheath sidewallsw h 1h 'ngage the side walls of saidgroove, being d r r ed'fin generally parallel relation, whereby there isno liability of said sheath turning in said groove.
